Abstract

If the arrow of time reverses in a recontracting universe it could produce observable electromagnetic effects. The authors argue that the existing observational data offer strong evidence against recent versions of time-symmetric universe models, assuming the universe is essentially transparent on the future light cone. They investigate this assumption for a simple recontracting Friedmann model.
